Dr. Theys joined the UW-Fond du Lac faculty in 2003 after teaching at UW-Fox Valley and UW-Oshkosh. His area of expertise is organic chemistry with emphasis on the use of organometallics for organic synthesis. In addition to his academic background, he has worked in industrial chemistry positions. This industry experience enables him to connect “real life” chemistry to theoretical chemistry in the classroom.

He studied the German language in Germany for two summers, one with Marquette University and another with Georgetown University. Dr. Theys is a member of the American Chemical Society and the Boy Scouts of America (Assistant Scoutmaster).

Away from the campus, Dr. Theys enjoys attending sporting events such as soccer, basketball and baseball, especially when any of his four children are participating. He and his family enjoy visiting national parks such as Glacier, Yellowstone, Grand Canyon, Zion and Mesa Verde in their pop-up camper. Dr. Theys also enjoys being involved in his church and his children's school activities.

When not engrossed in a chemistry textbook, he enjoys reading fictional novels by authors such as J.R.R. Tolkien and Terry Brooks. He and his wife enjoy going out to the Adler Brau in Appleton for a Dopplebock.
